Alpha Status, Dominance, And Division Of Labor In Wolf Packs, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The prevailing view of a wolf (Canis lupus) pack is that of a group of individuals ever vying for dominance but held in check by the “alpha” pair, the alpha male and alpha female. Most research on the social dynamics of wolf packs, however, has been conducted on non-natural assortments of captive wolves. Here I describe the wolf-pack social order as it occurs in nature, discuss the alpha concept and social dominance and submission, and present data on the precise relationships among members in free-living packs, based on a literature review and 13 summers of observations of wolves …

Three captive muskoxen (Ovibos moschatus) were successfully infected with third-stage larvae of Umingmakstrongylus pallikuukensis digested or emerged from the slugs Deroceras reticulatum and D. laeve, for the first time completing the life cycle of this parasite under experimental conditions. The course of parasite development and patency was followed for 26 months post infection (p.i.) using fecal examinations and radiography. The prepatent periods in two of the muskoxen were 91 and 95 days and the patent period in one extended for 23 months. Larval production peaked 13–14 months p.i. On postmortem of two of the muskoxen at months …

The Chondrocranium Of The Mexican Burrowing Toad, Rhinophrynus Dorsalis, Charles C. Swart, Rafael O. De Sá

Biology Faculty Publications

The chondrocranium of Rhinophrynus dorsalis is described and illustrated. Autapomorphies of R. dorsalis are the presence of the symplectic cartilage and a cartilaginous process on the ascending process of the palatoquadrate. Synapomorphies of Rhinophrynus shared with the Pipidae are: (1) early formation of the lower jaw and (2) presence of a suprarostral plate. Alternative developmental pathways for the formation of the suprarostral plate are considered. Histological data indicates that the suprarostral plate forms from: (1) the early fusion of the cornua trabeculae with the suprarostral cartilages, (2) an anterior growth of the ethmold plate, and (3) subsequent fusion …

Unidad De Los Anfibios Modernos Como Grupo Natural, Rafael O. De Sá

Biology Faculty Publications

RESUMEN

La monofilia de la infraclase Lissamphibia ha sido cuestionada. Algunos autores sugieren un origen independiente del Orden Gymnophiona basados en la condición compacta (= estegocrotafía) del cráneo de la cecilias. La presente revisión indica la irrelevancia del estegocrotafismo para establecer las relaciones filogenéticas del grupo. Los datos disponibles sugieren: 1) el estegocrotafismo es secundariamente derivado en cecilias, y 2) Lissamphibia representa un grupo monofilético.

SUMMARY

Unity of modern Amphibians as a natural group

The monophyly of Lissamphibia has been previously questioned. Some authors suggested an independent origin of Gymnophiona based on the solid condition (= stegokrotaphy) of the caecilian …

Characterization And Structure-Function Studies Of Human Liver Flavin Monooxygenase Isozyme 3 (Fmo3), Orhan Adali, Richard M. Philpot

Turkish Journal of Zoology

The activity of the flaving-containing monooxygenase (FMO EC 1.14.13.8) can be modulated by a number of nitrogen-containing compounds in a manner that is both isoform and effector-dependent. We showed that the direction (activation or inbihiton) and extent of modulation can also be dependent on substrate concentration. The native human liver FMO3 and arg 433 mutant FMO3 catalyze the methimazole reaction with similar Km values. However, the mutant FMO3-catalyzed reaction was affected differently by high concentration of imipramine, imipramine causing inhibition of activity. Our results suggest that the response of FMO3 to imipramine involves a distribution of compounds between two sites …

Turkish Journal of Zoology

The effects of eyestalk ablation on maturation, moulting and spawning in Penaeus semisulcatus were investigated in this study. Twelve males and 12 eyestalk-ablated and 12 non-ablated, all individually marked females were stocked into a 12-ton maturation tank. All the ablated females moulted in 9.08±1.68 days and first spawning occurred 16.75±3.41 days following eyestalk ablation. While all the ablated females spawned, producing an average of 177.000 ±133.340 eggs, only three non-ablated females spawned, producing average of 23.216±16.957 eggs during a period of 45 days (P0.05). Average nauplii production per female was 81.574±55.126 for ablated and 13.397±11.535 for non-ablated ones (P

Two New Sex Determining Factors ( M V , F D ) In Housefly, (Musca Domestica) Populations In Turkey, Şükran Çakir

Turkish Journal of Zoology

In most strains of the common housefly, Musca domestica, sex is genetically determined by the presence or absence of a Y chromosome with a dominant male determining factor, M. Standard trains have an XX-XY mechanism. In certain laboratory and natural populations, however, neither females nor males have the Y chromosome. These non-standard populations have autosomal mechanisms for sex determination. In the present study, the existence of two new autosomal sex determining factors, M V and F D , in housefly populations in Turkey was determined.
